OBJECTIVETo evaluate the inhibitory effect of high mobility group chromosomal protein N2 (HMGN2) on human tongue carcinoma tumor in nude mice.

METHODSA transplantation tumor model in nude mice was constructed by injecting Tca8113 cells. After a week, negative control groups, masculine control groups, and HMGN2 groups were established. Cell culture of the three groups were separately injected with washing buffer II, cis-dichlorodiamineplatinum (DDP), and HMGN2 protein. The tumors were moved after four treatments, and then analyzed by hematoxylin-eosin (HE) staining.

RESULTSA transplanted tumor model was established successfully. The volumes of HMGN2 groups and masculine control groups were smaller than those of the negative groups. Mouse weight did not differ among the three groups. Average tumor weight of the negative group was (0.38 +/- 0.19)g, that of the HMGN2 group was (0.21 +/- 0.15)g, and that of the DDP group was (0.23 +/- 0.16)g. These factors indicated no statistically significant difference among the three groups. The tumor inhibitory rate of HMGN2 group was 45.71%, and that of the positive group was 39.44%. Based on evaluation by naked eye, the tumor in the negative group was larger than that in other groups. In addition, cell necrosis was observed during HE staining.

CONCLUSIONHMGN2 could significantly inhibit growth of the transplanted tumor in nude mice.

Objective To observe the degree of joint flexion and extension of elbow and knee joints of moderate skeletal fluorosis patients before and after treatment and to assess the effects of Gun's MaQian decoction in treating moderate skeletal fluorosis. Methods 54 moderate skeletal fluorosis patients were randomly recruited into a treatment group and a control group. The treatment group was treated with Gun's MaQian decoction initially, and changed to be treated with GuKangNing capsule after 8 weeks' treatment. The control group was treated with placebo at first, and also changed to be treated with GuKangNing capsule after 8 weeks. Results Joint flexion and extension of elbow was improved greatly in both groups after the treatment, while the treatment group showing better effects than the control group (P<0.05). The improvement of joint flexion and extension of knee had not showed a statistical significance after the treatment. A 24 weeks follow-up to the joint flexion and extension of both elbow and knee revealed obvious improvement and the difference between the two groups were significance (P<0.05). Conclusion Gun's MaQian decoction can improve the flexion and extension of elbow and knee in moderate skeletal fluorosis patients.

Objective:To explore the expression and clinical significance of IL-1β and IL-1β receptor antagonist(IL-1ra)in persistent pulmonary hypertension of the newborn(PPHN)secondary to sepsis.Methods:The newborns with sepsis were enrolled in the Department of Neonatal Intensive Care Unit(NICU)of Xi′an Children′s Hospital from January 2018 to November 2020.The newborns with sepsis were divided into two groups: the newborns without PPHN( n=108)were the control group and the newborns with PPHN( n=44)were the experimental group.Clinical data, laboratory examination and bedside echocardiography of all the newborns were collected to analyze the differences between the two groups.The expression levels of IL-1β and IL-1ra in neonatal plasma of the two groups were detected by enzym-linked immunosorbination(ELISA), and their roles in neonatal sepsis with PPHN were further analyzed.The risk factors of neonatal sepsis with PPHN were analyzed by multivariate Logistic regression, and the early prediction value of the risk factors for neonatal sepsis with PPHN were evaluated by the receiver operating characteristic(ROC)curve. Results:There were no significant differences in gestational age[(39.11±0.55)w vs(38.85±0.72)w], birth weight[(3.30±0.49)kg vs(3.24±0.55)kg]and proportions of males[60(55.6%)vs 30(68.2%)]between the two groups( P>0.05). The right ventricular diameter[(9.57±0.35)mm], pulmonary artery pressure[(51.36±5.91)mmHg]and the level of N-terminal brain natriuretic peptide(NT-proBNP)[(25436.83±12343.18)ng/L)]significantly increased in the experimental group than those in the control group[(8.77±0.41)mm, (31.24±5.11)mmHg, (11267.09±4405.48)ng/L, respectively, P<0.05]. Before treatment, the expression levels of plasma IL-1β[(31.24±5.25)ng/L]and IL-1ra[(41.94±10.13)ng/L]in the experimental group were significantly higher than those in the control group[(18.27±4.47)ng/L, (21.47±8.76)ng/L, respectively, P<0.05]. The expression levels of plasma IL-1β[(10.46±3.17)ng/L]and IL-1ra[(10.58±2.94)ng/L]in the experimental group after treatment were significantly lower than those before treatment[(31.24±5.25)ng/L, (41.94±10.13)ng/L , respectively, P<0.05]. Multivariate Logistic regression analysis showed that IL-1β and NT-proBNP were the independent risk factors for neonatal sepsis with PPHN( P<0.05). ROC curve analysis showed that IL-1β and NT-proBNP had the good predictive value for the occurrence of neonatal sepsis with PPHN( P<0.05). IL-1β combined with NT-proBNP has the better predictive value for neonatal sepsis with PPHN. Conclusion:IL-1β combined with NT-proBNP have the high predictive value for PPHN of the newborns secondary to sepsis.

Objective? To investigate the correlation between post traumatic growth, social support and resilience in patients with breast cancer, and to provide reference for intervention programme on enhancing positive psychological quality. Methods? Totally 180 patients with breast cancer from 4 ClassⅢ Grade A hospitals in Jiangsu Province were selected by convenience sampling method from June to October in 2018. They were investigated with General Information Questionnaire, Post Traumatic Growth Inventory (PTGI), Social Support Rating Scale (SSRS), and Connor-Davidson Resilience Scale (CD-RISC). Results? In breast cancer patients, the total scores of PTGI, SSRS and CD-RISC were (62.52±17.59), (35.15±9.29) and (56.51±18.33) scores. Correlation analysis showed that the total scores of PTGI and its each dimension were positively correlated with the total scores of SSRS, as well as the total scores of CD-RISC and its each dimension (P＜0.01); the total scores of SSRS and its each dimension were positively correlated with the total scores of CD-RISC and its each dimension (P＜ 0.01). Multivariate linear regression analysis showed that resilience, methods of disease detection, and treatment plans were independent influencing factors of PTG in patients with breast cancer. Both social support and resilience could positively predict PTG, whose path coefficients were 0.493 and 0.302, respectively. Resilience was a mediator of social support and PTG. The indirect effect was 0.080. Conclusions? Resilience plays an important role in mediating between social support and PTG in patients with breast cancer. The resilience training could promote patients' PTG ability .

Objective? To assess the application effects of internet-delivered cognitive-behavioral therapy(ICBT) on symptom management in cancer patients. Methods? All randomised controlled trials (RCTs) about applying ICBT in symptom management in cancer patients in the following databases were searched from the establishment date up until 20th August 2018: Web of Science, PubMed, Cochrane Library, Embase, CBMdisc, Chinese National Knowledge Infrastructure databases(CNKI) and Wanfang. After literature screening, data extraction and quality evaluation, RevMan 5.3 software was used for meta-analysis. Results? Finally, 11 RCT studies were included, totaling 2329 subjects. The results showed that ICBT was beneficial to improve mental distress [SMD=5.02, 95%CI (0.80, 9.25), P=0.02], sleep quality [SMD=0.35, 95%CI (0.02, 0.68), P=0.04]and cancer-related fatigue [SMD=0.50, 95%CI (0.01, 0.99), P=0.04]; but ICBT did not have depression relieving effects in cancer patients (P＞0.05). Conclusions? ICBT is beneficial to reduce psychological pain, improve sleep quality and alleviate cancer-related fatigue in cancer patients, but it has no obvious advantage in alleviating depression. Future studies still need to focus on specific cancer types and validate them with multi-center, large-sample and long-term intervention studies.
